Double diaper system

Abstract

A double diaper package includes adhesively attached, similarly sized inner and outer diapers. Each of the diapers has a liquid permeable skin contacting net and a liquid impermeable polymeric back sheet edge bonded to each other so as to surround and encase a super-absorber in a fibrous matrix. The inner diaper has an adhesive coated edge flap of the liquid impermeable sheet extending from the edge bond. This edge flap secures the outer diaper to the inner diaper, forming a double diaper package that is attached to the baby using waist-securing tabs connected to the inner diaper. When soiled, the inner diaper is pulled away by releasing the waist-securing tabs and the adhesive edge flap attachment. The fresh, clean, outer diaper is attached using the waist-securing tabs of the outer diaper. The inner soiled diaper is then discarded.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to diapers; and, more particularly, to a diaper system wherein a plurality of diapers comprising an inner diaper and an outer diaper are attached to each other so that the soiled inner diaper may be readily removed to thereby expose a fresh outer diaper.[0003]2. Description of the Prior Art[0004]A number of prior art patents relate to the use of multiple layered diapers. These multiple layers allow improved absorption of liquids and do not constitute separate diapers. Liquid retaining capacity is oftentimes absent, since the strength and size these multiple layered diapers is generally inadequate to meet the required level of urine absorption.[0005]U.S. Pat. No. 4,022,210 to Glassman discloses a disposable diaper having a supplemental insert. This disposable diaper has a removable laminated supplemental insert formed with a pull tab to permit its separation from the diaper. Both the diaper ...

AI Technical Summary

Benefits of technology

This system significantly reduces the effort and time required for diaper changes, keeping the outer diaper clean and fresh, even in limited facilities, by using super-absorbers that absorb 50 to 100 times their weight, preventing urine migration and maintaining hygiene.

Problems solved by technology

Liquid retaining capacity is oftentimes absent, since the strength and size these multiple layered diapers is generally inadequate to meet the required level of urine absorption.

Due to the small size of the insert, the liquid discharged by the baby tends to overwhelm the liquid capturing capacity of the insert.

The insert does not contain moisture absorption superabsorbers and therefore has only limited fluid absorption capability.

The underlying diaper may therefore be soiled and removal of the insert does not guarantee a fresh diaper underneath.

Due to the small size of the insert, the liquid discharged by the baby tends to overwhelm the liquid capturing capacity of the insert.

The plastic flaps provided occupy the area surrounding the small insert and do not provide moisture absorption capability.

It has limited fluid absorption capability, with the result that the underlying diaper is frequently soiled.

Accordingly, removal of the insert does not guarantee a fresh diaper underneath.

If the liner absorption capability is completely exhausted, the over-garment will become soiled.

No means are provided to expose the soiled absorbent pad, or to pull it away to expose a fresh absorbent pad.

There is no means provided to quickly remove a soiled diaper while exposing a fresh diaper.

A diaper with this capability would be extremely useful during traveling or shopping situations, where changing a baby takes substantial time and effort and facilities that accommodate a full diaper change and cleaning operation are limited.
